+		<listitem><para>This option allows the administrator to chose which backends to retrieve and store passwords with. This allows (for example) both 
+                smbpasswd and tdbsam to be used without a recompile. 
+                Multiple backends can be specified, separated by spaces. The backends will be searched in the order they are specified. New users are always added to the first backend specified.
+                Experimental backends must still be selected
+                (eg --with-tdbsam) at configure time.

+                        on the samba server - even when the user doesn't have a 'real' samba account in one of the 
+                        other passdb backends.
+			</para>
+
+			<para>This backend should always be the last backend listed, since it contains all users in 
+                        the unix passdb and might 'override' mappings if specified earlier. It's meant to only return 
+                        accounts for users that aren't covered by the previous backends.</para>
